Canada’s efforts in healthy housing are based mainly in various low energy house programs. Since the early 1980s, Natural Resources Canada has launched two major programs to promote the construction of energy efficient or low energy houses (Mayo and Sinha 1996, Sinha 1996). The first one is the R-2000 program that was established in 1982. The performance target for R2000 houses was based on a 5...

no trace of the wild talk to which some of his followers have accustomed us. To demand " millions of houses " in the twinkling of an eye is to cry for the moon. If thousands of millions of money were available for the purpose to-morrow the thing could not be done. Men are as essential as money, and men at present are not forthcoming. It is true that the'Prime Minister is sanguine of being able,...

We propose a dynamic model for optimizing the ows of atcars that considers explicitly the broad range of complex constraints that govern the assignment of trailers and containers to a atcar. The problem is formulated as a logistics queueing network which can handle a wide range of equipment types and complex operating rules. The complexity of the problem prevents a practical implementation of a...

in the architecture of iranian traditional houses, the ornamentations available in the inscriptions of houses entrance portal express the identity of architects and personality of houses owners and are rooted in their religious and national beliefs and faiths. the main hypothesis of this research is changing the physique and application of religious contents in compliance with the thoughts and ...

Fix an odd integer d ≥ 1 and let Fd ⊂ R2 denote the real Fermat curve defined by the equation xd + yd = 1. Here we prove that Fd has the following property: Let X ⊆ Rn be any real algebraic variety. Then there exists a “one-parameter isotopic Nash modification” X̃t of X such that X̃0 = X and each real algebraic variety X̃t, t = 0 may be biregularly embedded into (Fd). Mathematics Subject Classific...

We consider the situation of rearranging freight trains in a shunting yard with a hump and several tracks. Here, an elementary shunting operation is to push a all cars of one track over the hump. On the way back to the tracks the cars can be guided individually to an arbitrary track. The goal is to create one or several trains that have their cars in a particular order. We measure the efficienc...

and Applied Analysis 3 in the middle variable, and associative in the sense that x, y, z,w, v x, w, z, y , v x, y, z , w, v , and satisfies ‖ x, y, z ‖ ≤ ‖x‖ · ‖y‖ · ‖z‖ and ‖ x, x, x ‖ ‖x‖ see 45, 47 . Every left Hilbert C∗-module is a C∗-ternary algebra via the ternary product x, y, z : 〈x, y〉z. If a C∗-ternary algebra A, ·, ·, · has an identity, that is, an element e ∈ A such that x x, e, e ...

The logistics operation of container terminal can be exploded into several subsystems which are correlative, these subsystems connect by some handling facilities. This paper study the coordinated scheduling of three main kinds of facilities-Quay Crane(QC),Yard Truck(YT) and Yard Crane(YC), use multidisciplinary variable coupling design optimization method(MVCDO) to build YT coordinated scheduli...
